Gulf Stream annual cycle from Spray underwater glider measurements, 2015-2023, Daily

Three-dimensional estimates of the time-mean and annual cycle of temperature, salinity, density, and velocity derived from Spray glider observations in and near the Gulf Stream along the US East Coast. Date range of observations fitted is from JUL-16-2015 and MAY-30-2023 as indicated in the global attributes time_coverage_start and time_coverage_end. The number of annual harmonics fit is two as indicated by the global attribute n_harmonic. The underlying observations are available under DOIs https://doi.org/10.21238/S8SPRAY2675 and https://doi.org/10.21238/S8SPRAY0880.
